Nice idea!
The picture is already almost unusable while you have something like 3300 cars featured. Do you have any thought on how to deal with that problem?
Yeah, it's pretty busy with all of them together, but I assume that usually people want a specific brand (and often a specific model of that brand). I will add more filters soon - by year, location, model.
Location and any other filters (particular makes/models or years or price ranges) would help with that.
A front door of a site like this could have a screen cap, filter and then some quick-to-click pre-filters (Toyota SUVs made after 2005, or station wagons under $8k, etc).
